I research calibration techniques for projection-based displays, with a focus on techniques for continuous calibration.
The goal of my work is to create wide-area displays composed of multiple projectors, where the imagery of the different devices
is aligned automatically and continuously during use to create a single, uniform display that also compensates for the shape
of a potentially complex display surface.

High-resolution displays of this type are necessary for producing the immersive visuals and sense of presence required
in virtual environments and simulation. These displays are typically constructed using an array of projectors to form a large,
tiled display that is visually seamless. As you can see in this image, however, the surfaces that can be used for display are not limited
to being a single plane, but can instead be made up of multiple different walls of a room. By pre-warping the images projected
by the projectors, it is possible to make the image appear correct from the viewpoint of the user.
